CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 10-2014-0032165, filed on Mar. 19, 2014, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

BACKGROUND

1. Field

One or more embodiments of the present disclosure relate to a condensed cyclic compound and an organic light-emitting device including the same.

2. Description of the Related Art

An organic light-emitting device may have a structure in which a first electrode, a hole transport region, an emission layer, an electron transport region, and a second electrode are sequentially disposed in this order on a substrate. Holes injected from the first electrode move to the emission layer via the hole transport region, while electrons injected from the second electrode move to the emission layer via the electron transport region. Carriers such as the holes and electrons recombine in the emission layer to generate exitons. When the exitons drop from an excited state to a ground state, light is emitted.

Hereinafter, a structure of an organic light-emitting device according to an embodiment of the present disclosure and a method of manufacturing the same will now be described with reference to FIG. 1.

FIG. 1 is a schematic sectional view of an organic light-emitting device 10 according to an embodiment of the present disclosure. Referring to FIG. 1, the organic light-emitting device 10 includes a first electrode 110, an organic layer 150, and a second electrode 190.

A substrate (not shown) may be disposed under the first electrode 110 or on the second electrode 190 in FIG. 1. The substrate may be a glass or transparent plastic substrate with good mechanical strength, thermal stability, transparency, surface smoothness, ease of handling, and water resistance.

For example, the first electrode 110 may be formed by depositing or sputtering a first electrode-forming material on the substrate 11. When the first electrode 110 is an anode, a material having a high work function may be used as the first electrode-forming material to facilitate hole injection. The first electrode 110 may be a reflective electrode, a semi-transmissive electrode, or a transmissive electrode. Transparent and conductive materials such as ITO, IZO, SnO₂, and ZnO may be used to form the first electrode. The first electrode 110 as a semi-transmissive electrode or a reflective electrode may comprise at least one material selected from magnesium (Mg), aluminum (Al), aluminum-lithium (Al—Li), calcium (Ca), magnesium-indium (Mg—In), and magnesium-silver (Mg—Ag).

The first electrode 110 may have a single-layer structure or a multi-layer structure including a plurality of layers. For example, the first electrode 110 may have a three-layered structure of ITO/Ag/ITO, but is not limited thereto.

For example, the electron transport layer may include at least one of a hole blocking layer (HBL), an electron transport layer (ETL), and an electron injection layer (EIL). However, embodiments of the present disclosure are not limited thereto.

The hole transport region may have a single-layered structure including a single material, a single-layered structure including a plurality of materials, or a multi-layered structure including a plurality of layers including different materials.

In some embodiments, the electron transport region may have a single-layered structure including a plurality of materials, or a multi-layered structure of HIL/HTL, HIL/HTL/buffer layer, HIL/buffer layer, HTL/buffer layer, or HIL/HTL/EBL, wherein these layers forming a multi-layered structure are sequentially disposed on the first electrode 110 in the order stated above. However, embodiments of the present disclosure are not limited thereto.

When the hole transport region includes a HIL, the HIL may be formed on the first electrode 110 by using any of a variety of methods, for example, by using vacuum deposition, spin coating, casting, Langmuir-Blodgett (LB) deposition, inkjet printing, laser printing, laser induced thermal imaging (LITI), or the like.

When the HIL is formed using vacuum deposition, the deposition conditions may vary depending on the material that is used to form the HIL and the structure of the HIL. For example, the deposition conditions may be selected from the following conditions: a deposition temperature of about 100° C. to about 500° C., a degree of vacuum of about 10⁻⁸to about 10⁻³torr, and a deposition rate of about 0.01 to 100 Å/sec.

When the HIL is formed using spin coating, the coating conditions may vary depending on the material that is used to form the HIL and the structure of the HIL. For example, the coating conditions may be selected from the following conditions: a coating rate of about 2,000 rpm to about 5,000 5 pm and a heat treatment temperature of about 800° C. to about 200° C.

When the hole transport region includes a HTL, the HTL may be formed on the first electrode 110 or the HIL by using any of a variety of methods, for example, by using vacuum deposition, spin coating, casting, Langmuir-Blodgett (LB) deposition, inkjet printing, laser printing, laser induced thermal imaging (LITI), or the like. When the HTL is formed using vacuum deposition or spin coating, the conditions for deposition and coating may be similar to the above-described deposition and coating conditions for forming the HIL, and accordingly will not be described in detail.

In Formulae 201A and 201A-1, R₂₁₃and R₂₁₄may be linked to each other to form a saturated or unsaturated ring.

The compound represented by Formula 201, and the compound represented by Formula 202 may be compounds HT1 to HT20 illustrated below, but are not limited thereto.

A thickness of the hole transport region may be from about 100 Å to about 10000 Å, and in some embodiments, from about 100 Å to about 1000 Å. When the hole transport region includes a HIL and a HTL, a thickness of the HIL may be from about 100 Å to about 10,000 Å, and in some embodiments, from about 100 Å to about 1,000 Å, and a thickness of the HTL may be from about 50 Å to about 2,000 Å, and in some embodiments, from about 100 Å to about 1,500 Å. When the thicknesses of the hole transport region, the HIL, and the HTL are within these ranges, satisfactory hole transport characteristics may be obtained without a substantial increase in driving voltage.

The hole transport region may further include a charge-generating material to improve conductivity, in addition to the materials as described above. The charge-generating material may be homogeneously or inhomogeneously dispersed in the hole transport region.

The charge-generating material may be, for example, a p-dopant. The p-dopant may be one of quinine derivatives, metal oxides, and compounds with a cyano group, but is not limited thereto. Non-limiting examples of the p-dopant are quinone derivatives such as tetracyanoquinonedimethane (TCNQ), 2,3,5,6-tetrafluoro-tetracyano-1,4-benzoquinonedimethane (F4-TCNQ), and the like, metal oxides such as tungsten oxide, molybdenum oxide, and the like; and Compound HT-D1 below.

The hole transport region may further include at least one of a buffer layer and an EBL, in addition to the HIL and HTL described above. The buffer layer may compensate for an optical resonance distance of light according to a wavelength of the light emitted from the EML, and thus may improve light-emission efficiency. A material in the buffer layer may be any material used in the hole transport region. The EBL may block migration of electrons from the electron transport region into the EML.

The EML may be formed on the first electrode 110 or the hole transport region by using any of a variety of methods, for example, by using vacuum deposition, spin coating, casting, Langmuir-Blodgett (LB) deposition, inkjet printing, laser printing, laser induced thermal imaging (LITI), or the like. When the EML is formed using vacuum deposition or spin coating, the deposition and coating conditions for forming the EML may be similar to the above-described deposition and coating conditions for forming the HIL, and accordingly will not be described in detail.

When the organic light-emitting device 10 is a full color organic light-emitting device, the EML may be patterned into a red emission layer, a green emission layer, and a blue emission layer to correspond to individual subpixels, respectively. In some embodiments, the EML may have a structure in which a red emission layer, a green emission layer and a blue emission layer are stacked upon one another, or a structure including a mixture of a red light-emitting material, a green light-emitting material, and a blue light-emitting material, and thus may emit white light.

The EML may include a host and a dopant.

For example, the host may include at least one of TPBi, TBADN, ADN (also referred to as “DNA”), CBP, CDBP, and TCP.

In some embodiments, the host may include a compound represented by Formula 301.

Example 1

A corning 15 Ω/cm²(1200 Å) ITO glass substrate was cut to a size of 50 mm×50 mm×0.7 mm and then sonicated in isopropyl alcohol and pure water each for five minutes, and then cleaned by irradiation of ultraviolet rays for 30 minutes and exposure to ozone. The resulting ITO glass substrate was mounted into a vacuum deposition device.

After 2-TNATA was vacuum-deposited on the ITO anode of the ITO glass substrate to form an HIL having a thickness of 600 Å, NPB was deposited on the HIL to form a HTL having a thickness of about 300 Å, and then DNA (host) and DPAVBi (dopant) were co-deposited in a weight ratio of 98:2 on the HTL to form an EML having a thickness of about 300 Å.

Then, Compound 1A was deposited on the EML to form an ETL having a thickness of about 300 Å, and then LiF was deposited on the ETL to form an EIL having a thickness of about 10 Å.
